Kuyisinyathelo sokuqala esephuza kodwa esicishe sihlale siveza isinyathelo sesibili esisheshayo.

I-LDPE, noma i-polyethylene enokuminyana okuphansi, iyi-thermoplastic ekhiqizwa yi-free-radical polymerization ye-ethylene ngaphansi kwengcindezi ephezulu, inqubo edala ukwakheka kwamangqamuzana anamagatsha esikhundleni samaketanga aqondile acwebile atholakala kwamanye ama-polyolefin. Lokho kuhlukaniswa yikho okwenza ukuminyana kwe-polyethylene enokuminyana okuphansi ngokuvamile kube phakathi kuka-0.910 no-0.925 g/cm³, okuyenza ibe ngenye yama-polymer asetshenziswa kakhulu emhlabeni wonke ancane kakhulu. Ukupakishwa okuxekethile kwamaketanga anamagatsha kunikeza i-LDPE ukuguquguquka kwayo okuyisici, i-crystallinity ephansi kanye nokuthamba, umuzwa onjenge-wax, izimfanelo ezingaxhashazwa abaguquli emafilimini, ekufakweni kwezingubo nasekusetshenzisweni kokubumba. Ngokwekhemikhali, le nto imelana nama-asidi anciphile, ama-base, ama-alcohol kanye nezixazululo eziningi zamanzi, nakuba ivuvukala lapho ihlangana nama-hydrocarbon kanye nama-oxidizing agents anamandla. Iphinde inikeze ukuhlukaniswa kukagesi okuhle kakhulu, ukumuncwa kwamanzi okuphansi kanye nokuqina komthelela okuhle ngisho nasemazingeni okushisa angaphansi kwe-zero. Lezi zimfanelo ezihlangene zichaza ukuthi kungani i-LDPE iseyinto eyisisekelo yokupakisha okuguquguqukayo ngemuva kweminyaka engaphezu kwengxenye yekhulu yokusetshenziswa kwezentengiselwano. Bambalwa ama-polymer alinganisa izindleko nokusebenza ngempumelelo kangaka.

I-LDPE iyagaywa kabusha ngokuphelele futhi inekhodi yokukhomba insalela engu-4, okubeka endaweni efanayo yokugaywa kabusha kwemishini njengamafilimu nezikhwama eziningi ezisetshenzisiwe. Ukucutshungulwa kulula: impahla isebenza emigqeni yamafilimu avuthelwayo, imishini yamafilimu athululwayo kanye neyokumboza nge-extrusion, imishini yokubumba nge-injection, imishini yokubumba nge-blow molding kanye nemigqa yokukhipha izintambo nezingcingo. Iwindi layo elibanzi lokucubungula libekezelela ukuhluka okulinganiselwe kwezinga lokushisa kanye nesivinini sesikulufu, okunciphisa amazinga okulahleka ngesikhathi sokuqala nokushintsha kwezigaba. Ngenxa yokuthi izinzile ngokushisa ngaphansi kwezimo ezijwayelekile, i-LDPE ikhiqiza ijeli encane noma ukuwohloka uma iqhathaniswa namanye ama-polymer azwela kakhulu ekushiseni. Abacubunguli bangaphinde bayixube ne-linear low density polyethylene ukuze kulinganiswe ukuzinza kwebhamuzi ngokumelene nokumelana nokubhobozwa. Lokho kuxubeka kungenye yezizathu zokuthi ukusetshenziswa kwe-ldpe kuqhubeke ngisho ngenkathi ama-polyolefin amasha engena emakethe. Kiphinde kunikeze abahlanganisi ithuba lokulungisa izakhiwo ngaphandle kokushintsha umndeni we-polymer oyisisekelo.

Lapho abathengi beqhathanisa i-hdpe ldpe kanye ne-linear low density polyethylene, izici ezinqumayo ngokuvamile ukuqina, ukuqina, ukucaca kanye nokuziphatha kokuvala. I-HDPE iqinile futhi ayibonakali, inokuminyana okungaphezu kuka-0.941 g/cm³, okwenza kufanele amabhodlela, amakhreyithi namapayipi lapho amandla esakhiwo abaluleke kakhulu kunokuguquguquka. I-Linear low density polyethylene ihlezi ebangeni lokuminyana elifana ne-LDPE kodwa isebenzisa amagatsha amafushane, alinganayo, okukhiqiza amandla aphezulu okudonsa kanye nokubhoboza ekujuleni okunikeziwe. I-LDPE inxephezelisa ngamandla ancibilikayo angcono, ukuzinza kwebhamuphu okuphezulu emigqeni yefilimu evuthelwayo kanye nokushisela okulula ekushiseni okusezingeni eliphansi. Empeleni, izakhiwo eziningi zokupakisha zihlanganisa zombili, zisebenzisa i-LLDPE ukuthola amandla kanye ne-LDPE ukucubungula kanye nokuqinisekisa ukuvala. Ukuqonda lezo zingxabano kuyisisekelo sayo yonke incazelo ehlakaniphile ye-resin. Umphakeli ongazichaza ngokucacile ubaluleke kakhulu kunalowo ovele asho inombolo ephansi kakhulu.

Ukusetshenziswa okukhulu kwe-LDPE oyedwa yifilimu, futhi kuleso sigaba impahla ibusa izikhwama zokuthenga, izikhwama zemikhiqizo, izikhwama zesinkwa, ifilimu enciphayo kanye nezinto zokugqoka ezinzima. Amabanga efilimu avuthelwayo ane-melt index ephakathi kuka-0.3 no-2 g/10 min anikeza ukuzinza kwebhamuza kanye nokudonswa okudingekayo kumagauge amancane, kuyilapho amabanga e-melt index aphezulu afanele ukumboza nge-extrusion kanye nokunamathisela. Ifilimu yezolimo, ukusonga i-silage kanye nezembozo zase-greenhouse nakho kuncike ku-LDPE ngoba imelana nokuklebhuka futhi ihlala ibhebhethekile phakathi nokushintshashintsha kwezinga lokushisa kwesizini. Izinto zokugqoka zezikhwama ezinzima kanye nezikhwama zezimboni zivame ukusebenzisa ingxube ye-LDPE ne-LLDPE ukuze kuhlanganiswe ukukwazi ukuvaleka namandla okuthwala umthwalo. I-Mier ihlinzeka ngamabanga efilimu anezinto zokuhamba ezilungiselelwe, zokuvimbela ukunamathela kanye ne-UV stabilizer kule misebenzi eyinselele yangaphandle neyokupakisha. TheUhlelo Lokusebenza ikhasi libonisa indlela lezo zinto ezisetshenziswayo ezihumusha ngayo zibe imikhiqizo yokugcina yangempela kuzo zonke izimboni. Abaguquli abafanisa izinga nge-gauge ngokucophelela banganciphisa ukusetshenziswa kwe-resin ngaphandle kokulahlekelwa ukusebenza.

Ngaphandle kwefilimu, i-LDPE isetshenziswa kabanzi ekubunjweni kwe-injection molding kumakhava, izivalo, izitsha kanye nezingxenye eziguquguqukayo ezidinga ukuqina hhayi ukuqina okungaguquki. Izinqubo ze-extrusion zihlanganisa ipayipi, ishubhu, iphrofayili kanye neshidi, lapho ukumuncwa kwamanzi okuphansi kwepolymer kanye nokumelana namakhemikhali kunikeza impilo yesevisi ende kuma-plumbing, ukunisela kanye ne-ducting yezimboni. I-extrusion coating isebenzisa ungqimba oluncane lwe-LDPE ephepheni, ebhodini naku-foil ukuze kuvinjwe umswakama ekupakishweni kokudla kanye namabhokisi oketshezi. Embonini yezintambo nentambo, i-LDPE isebenza njenge-insulation eyinhloko ngenxa yamandla ayo aphezulu e-dielectric, isici sokulahlekelwa okuphansi kanye nokusebenza kukagesi okuzinzile ngokuhamba kwesikhathi. I-cable jacketing kanye ne-semiconductive compounds nazo zifaka i-LDPE noma ama-copolymers ayo. TheUmdwebo wocingo ikhasi lichaza lezi zinhlelo zokusebenza ezihlobene nekhebula ngemininingwane eyengeziwe. Ngayinye yalezi zinhlelo zokusebenza ibeka izimfuneko ezahlukene ku-melt index, ngakho-ke ukukhethwa kwezinga kufanele ngaso sonke isikhathi kuqale ngenqubo hhayi uhlu lwamanani.

I-Custom formulation yilapho umhlinzeki ethola khona indawo yakhe encazelweni ebhaliwe. UMier angalungisa i-melt index, ukuminyana, amazinga okushelela nokuvimbela ukunamathela, ukuqiniswa kwe-UV, ukuvimbela umlilo, umbala kanye nengxenye yezinto ezisetshenzisiwe kabusha ukuze kuhambisane nomugqa wokucubungula wekhasimende kanye nezidingo zokusetshenziswa kokugcina. Ukuthuthukiswa kwenhlanganisela ngokuvamile kuqala ngengxoxo yobuchwepheshe, kulandelwe isampula yaselabhorethri, ukuhlolwa kokulinga bese kuba yiqoqo lokukhulisa elinezincazelo ezikhiyiwe. Njengoba uMier ebuye ahlanganise i-TPE, i-TPU kanye namapulasitiki obunjiniyela, angatusa izindlela ezixubile lapho ipholima eyodwa ingakwazi ukwanelisa izimfuno eziphikisanayo. Abathengi emkhakheni wezimoto nasezimpahleni zasendlini bavame ukuzuza kulombono wokuxuba izinto, njengoba izingxenye zabo zivame ukuhlanganisa izinto eziqinile neziguquguqukayo. Ithimba likaMier lithatha sonke isicelo esenziwe ngokwezifiso njengenkinga yencazelo okufanele ixazululwe kunokuba kube i-oda okufanele ligcwaliswe. Leso simo sengqondo sikhiqiza amazinga afanelekile, hhayi amazinga amane athunyelwe.

I-LDPE portfolio yakwa-Mier ihlanganisa amagreddi efilimu asetshenziswa nje, amagreddi acwebezelayo kakhulu okupakisha okuboniswayo, ama-resin okumboza ane-melt index ephezulu kanye namagreddi okubumba ngokufutha ane-melt index ephansi. Izinketho ze-melt index zihlanganisa ibhendi elidingwa kakhulu abaguquli, futhi ukuminyana kugcinwa ngaphakathi kwemikhawulo eqinile ukuze ukujiya, ukuqina kanye nokuziphatha kokuvala kuhlale kubikezeleka kusukela ku-lot kuya ku-lot. Amaphakethe ezithako ezengeziwe ahlanganisa ama-slip agents, anti-block, ama-antioxidants, ama-UV stabilizers kanye nezinhlelo ze-antistatic, konke kulinganiswa ngokohlelo oluhlosiwe lokusetshenziswa esikhundleni sokufakwa njengokuzenzakalelayo okujwayelekile. Igreddi ngayinye ilethwa ne-technical datasheet ebalisa ukuminyana, i-melt index, izakhiwo zokudonsa, i-Vicat softening point kanye namazinga okushisa okucutshungulwa anconyiwe. Lapho ikhasimende lidinga impahla engaphandle kwebanga elijwayelekile, ithimba lobuchwepheshe lakwa-Mier lizohlola inhlanganisela eyenziwe ngokwezifiso esikhundleni sokuphoqa ukuvumelana kwekhathalogi.

Umsebenzi wangokwezifiso uvamile ezinhlelweni zezimoto, izinto zasekhaya, ikhebula kanye nezokwelapha lapho amazinga ajwayelekile ehluleka khona. Izikhathi zokulinda zamakhompawundi amasha zincike ebunkimbini, kodwa i-Mier izicaphuna ngokucacile ngaphambi kokuba umsebenzi uqale. Inhloso ihlala iyigreyidi ezosebenza emgqeni, hhayi nje leyo ehlangabezana nencazelo yephepha.

Amanani amancane oku-oda ahlelwe ukuze asekele kokubili amaqembu amancane okuhlola kanye namavolumu aphelele eziqukathi, ukuze abathengi bakwazi ukuqinisekisa izinga ngaphambi kokuzibophezela ebuningini. Amaqembu agciniwe ngokuvamile athunyelwa phakathi nezinsuku, kuyilapho izinhlanganisela ezenziwe ngokwezifiso zilandela uhlelo lokukhiqiza okuvunyelwene ngalo oluqinisekiswa esikhathini sokunikezwa kwentengo. Izinketho zokupakisha zihlanganisa izikhwama ezingama-25 kg, izikhwama ezinkulu kanye nokulebula okwenziwe ngokwezifiso, konke kufakwa kuma-pallet ukuze kuzinze ekuthunyelweni kwamanye amazwe. Imibhalo yokuthumela kwamanye amazwe, izitifiketi zokuhlaziya kanye namashidi edatha yokuphepha kulungiselelwa njengokujwayelekile. I-Mier ixhumanisa ukuthutha kwempahla eya e-Asia, eYurophu, eNyakatho Melika nakwezinye izifunda ngokusebenzisa abalingani abasebenza nabo abagxilile kwezokuthutha. Abathengi abanomthamo ophindaphindwayo bangahlela ukulethwa okuhleliwe ukuze kuncishiswe kokubili ukugcinwa kwempahla kanye nengozi yokuphela kwempahla.

Ukucela isilinganiso, isampula noma idathashethi yezobuchwepheshe ku-Mier kulula futhi akubizi lutho ngaphandle kwengxoxo emfushane. Abathengi kufanele babelane ngendlela yabo yokucubungula, ukujiya okuhlosiwe noma isisindo sengxenye, inkomba yokuncibilika kanye nezintandokazi zokuminyana, kanye nanoma yiziphi izimfuneko zokulawula ukuze isincomo sifike sihlungiwe ngaphambili. Uma amanye amapharamitha esavulekile, onjiniyela bakwa-Mier bazophakamisa indawo yokuqala ngokusekelwe ezinhlelweni ezifanayo. Amasampula ngokuvamile athunyelwa ngokushesha, alandelwe idathashethi kanye nesiqondiso sokucubungula sokuhlola. Ngemuva kokuhlola, impendulo isetshenziselwa ukuqinisekisa noma ukucwenga izinga ngaphambi koku-oda kwezentengiselwano. Le ndlela ehlelekile isusa ukuqagela ekukhetheni izinto futhi inciphisa isikhathi sokukhiqiza. Iphinde idale irekhodi elibhaliwe elisekela izinga elingaguquki kukho konke ukulethwa okulandelayo.

Ukukhuluma nochwepheshe we-LDPE ekuqaleni kwephrojekthi cishe njalo konga imali kamuva, ngoba izinqumo zempahla zithinta amathuluzi, isivinini somugqa kanye nokuklanywa kwezinto zokupakisha. Ithimba lakwa-Mier lisekela amakhasimende kuzo zonke izinhlelo zefilimu, ukubunjwa, ukukhipha, ukumboza kanye nezintambo, futhi lingakweluleka ngezinhlanganisela, ukwehlisa usayizi kanye nezinketho zokuqukethwe okugaywe kabusha. Noma ngabe isidingo siyisikhwama esisodwa sokuhlola se-resin noma inkontileka yonyaka yeziqukathi eziningi, ukunakwa kobuchwepheshe okufanayo kuyasebenza. Xhumana nethimba nge-Xhumana Nathi ikhasi lokuqala ingxoxo yokucacisa. Ucingo olufushane mayelana ne-melt index namuhla lungavimbela ukuma komugqa okubiza kakhulu ngekota ezayo. I-Mier Plastic Material Co., Ltd. isilungele ukunikeza izinga elilidinga ngempela iphrojekthi yakho.
